This is a picture of Susan (left) and Mary (right). Imagine they have the same hairstyles, but bright red hair.
They wear what they wear in the cartoon.*
These girls are super geniuses. Of course they are twins, and they love science. Thought their inventions don't always work out, their intentions are good.
*For those of you who don't know, they are characters from a cartoon Johnny Test, and for the most part, their personalities will be the same.
